Hi, a few questions for you:-

Please post a photo of the LNBs as they are on the dish.

Make a note of the wires coming from the LNBs and check which position they go to on the Diseqc switch.

Also, go to the satellite setup menu, and find out what Diseqc1.0 switch positions you have set for the satellites you originally had working.

I suspect either your dish has moved in the wind, or someone has fiddled with the Diseqc switch positions. But to confirm, we need to know what you have setup.
